[0004] Currently, replacing the jet pipe in traditional equipment requires disassembling multiple sets of connecting components, which is cumbersome and time-consuming. It cannot be adapted to condenser pipes of different diameters. Multiple sets of special jet pipes need to be carried, increasing the burden of carrying tools. Moreover, there is no positioning and sealing structure, which makes it easy for misalignment or air leakage to occur during connection, resulting in high-pressure airflow loss, reducing unblocking efficiency, and affecting maintenance progress. Traditional equipment can only be placed randomly on the ground or in a toolbox, which takes up space and is inconvenient to access. The disorganized tools at the maintenance site can easily cause delays in access, and the equipment is not fixed and protected, making it susceptible to collision damage to components, shortening its service life. It cannot be stored in an orderly manner, reducing the convenience of HVAC system operation and maintenance. Utility Model Content

A locking groove 9 is provided, which cooperates with the replacement block 16. The initial circumferential positioning of the connecting sleeve 6 and the replacement sleeve 11 is achieved by rotational engagement. The auxiliary thread 7 and nut 8 complete the locking. One end of the connecting sleeve 6 is provided with an air jet pipe 10, and one end of the air jet pipe 10 is fixedly connected to the replacement sleeve 11. The replacement block 16 is fixedly connected to the outer wall of the replacement sleeve 11. The outer wall of the replacement block 16 is slidably connected to the inner wall of the locking groove 9. The inner wall of the connecting sleeve 6 is fixedly connected with a stabilizing ring 17. A spring 18 is fixedly connected to one side of the stabilizing ring 17. A sliding ring 19 is fixedly connected to one side of the spring 18. The outer wall of the sliding ring 19 is slidably connected to the inner wall of the connecting sleeve 6.

[0013] Reference Figure 1 , Figures 4-6 The wall-mounted assembly 2 includes a wall-mounted ring 12. The wall-mounted assembly 2 enables wall-mounted storage of the drain cleaner. Through the cooperation of the wall-mounted ring 12, wall hook 13, and locking assembly 14, the device can be easily fixedly stored on a wall at a service station or on-site. A wall hook 13 is fixedly connected to one side of the wall-mounted ring 12, and a locking assembly 14 is fixedly connected to the other side of the wall-mounted ring 12. The locking assembly 14 includes a rack 15, one side of which is fixedly connected to the outer wall of the wall-mounted ring 12. The locking assembly 14 also includes a rack box 20, one side of which is fixedly connected to the outer wall of the wall-mounted ring 12. Rack grooves 2 are formed on both outer walls of the rack box 20. 1. The rack box 20 is fixed to the outer wall of the wall-mounting ring 12 and houses the second rack 22 inside. Rack grooves 21 are opened on both sides for the first rack 15 to slide, forming the load-bearing structure of the locking assembly 14. The rack box 20 is provided with the second rack 22 inside. The top of the second rack 22 is fixedly connected to the locking block 23. The top of the locking block 23 is fixedly connected to the hinge 24. The inner wall of the hinge 24 is fixedly connected to the fixing rod 25. The outer wall of the fixing rod 25 is provided with the return spring 26. The top of the locking block 23 is fixedly connected to the lever 27. The first rack 15 is slidably connected to the inner wall of the rack groove 21. The outer wall of the first rack 15 is engaged with the outer wall of the second rack 22.

[0014] Working Principle: First, tank 1 serves as a compressed air storage unit, providing a power source for the unblocking operation. Pressure gauge 3 monitors the air pressure inside tank 1 in real time, ensuring the pressure remains within the effective unblocking range. During unblocking, pipeline 4 delivers the high-pressure gas from tank 1 to quick-change assembly 5: the thread 7 on the outer wall of connecting sleeve 6 engages with nut 8, forming a radial mechanical lock; the replacement block 16 on the outer wall of replacement sleeve 11 simultaneously engages with the locking groove 9 of connecting sleeve 6, achieving circumferential anti-rotation positioning. Simultaneously, the stabilizing ring 17 on the inner wall of connecting sleeve 6 supports the sliding ring 19 via spring 18, applying axial preload to the inserted replacement sleeve 11 to aid sealing and prevent air leakage. Finally, jet pipe 10 directs the high-pressure airflow to the blockage in the condenser pipe, using the impact force of the airflow to disperse and engulf the blockage, completing the unblocking process.

[0015] The wall-mounting assembly 2 and the locking assembly 14 work together to achieve device storage and adaptation: the wall-mounting ring 12 is fitted onto the outer wall of the tank body 1, and the wall hook 13 on one side is used to hook onto the wall hanging structure to form a suspension fulcrum; the locking assembly 14 on the other side adjusts the position of the wall-mounting ring 12 through rack engagement and locking block linkage. The first rack 15 slides into the rack groove 21 of the rack box 20, and the spacing of the wall-mounting rings 12 can be adjusted along the axial direction of the tank body 1; the second rack 22 in the rack box 20 engages with the first rack 15, and the top locking block 23 is hinged to the fixing rod 25 through the hinge 24. The return spring 26 is fitted onto the fixing rod 25 to provide a rebound force, so that the locking block 23 locks the second rack 22 in the normal state. When lever 27 is turned, locking block 23 rotates around hinge 24 to unlock, and rack 15 can slide freely to adapt to suspension requirements; after lever 27 is released, return spring 26 drives locking block 23 to reset, relocking rack 22 and rack 15 to re-lock the meshing state, ensuring that wall-mounted ring 12 firmly clamps tank 1, realizing the switching between wall-mounted storage and quick access of the device.

[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
